So I am quite new to python and have been working on this assignment for a week now on and off and can't quite get it to run correctly. I am now getting errors that tell me the function get_in_code is not defined although I've defined it. Any help would be greatly appreciated!

Python is a interpreted language. You need to define function prior to its usage. Just move a function definitions at the top of a file.
The problem is also with indentation. You're defining your methods inside while, just after a return statement. Actual functions aren't defined at all - interpreter doesn't reach those lines.
Besides, the code is "dirty". Split the code into separate classes/modules. Create well defined areas of responsibility, that would improve the code and it'll be easier to work with it.

I have been experimenting with creating an investment calculator, and I want to print the annual totals as well as the annual compounded interest. It's doing the annual totals fine, but not the annual interest. My inputs are $10000.00 principle, at 5% interest over 5 years.
start_over = 'true'
while start_over == 'true':
principle = int(input("Type the amount you are investing: "))
rate = float(input("Type interest rate"))
addition = int(input("Type annual Addition"))
time = int(input("Enter number of years to invest"))
real_rate = rate * 0.01
i = 1
print('total', principle * (1 + real_rate))
while i < time:
principle = (principle + addition) * (1 + real_rate)
i = i + 1
print('total', principle)
for i in range(time):
amount = i * (((1 + rate/100.0) ** time)) * principle
ci = amount - principle
i += 1
print("interest = ",ci)
redo_program = input('To restart type y or to quit type any key ')
if redo_program == 'y':
start_over = 'true'
else:
start_over = 'null'
Here are my outputs:
Type the amount you are investing: 10000
Type interest rate5
Type annual Addition0
Enter number of years to invest5
total 10500.0
total 10500.0
total 11025.0
total 11576.25
total 12155.0625
interest = -12155.0625
interest = 3358.21965978516

interest = 34384.78397935548
interest = 49898.06613914064
To restart type y or to quit type any key
Give this a go:
# Calculate year's values based on inputs and the current value of the account
def calc(current, addition, rate, year):
multiplier = 1 + rate/100 # The interest multiplier
new_total = (current + addition) * multiplier # Calculate the total
interest = round((new_total - current - addition), 2) # Interest to nearest penny/cent
return new_total, interest
def main():
# Inputs
principle = int(input("Type the amount you are investing: "))
rate = float(input("Type interest rate: "))
addition = int(input("Type annual Addition: "))
invst_time = int(input("Enter number of years to invest: "))
# Sets current account value to principle
current = principle
# Prints values for each year of investment
for i in range(invst_time):
total, interest_gained = calc(current, addition, rate, i+1)
print("At the end of Year: ", i+1)
print("Total: ", total)
print("Interest: ", interest_gained)
print("------")
current = total # Updates value of account

while 1:

main()

PFB the below code I am trying to calculate tax. why do I get the NameError: name 'tax' is not defined.
I have defined tax below still it throws the error tax not defined.
hw = float(input("Please enter total hours worked"))
hp = float(input("Please enter the hourly rate"))
# Pay and OT Calculations
rp = hp * hw
if hw == 40 or hw <40 :
ot = 0
tp = rp + ot
elif hw > 40 and hw <50 :
ot = (hw-40)*(hp*1.5)
tp = rp + ot
elif hw > 50 and hw < 60 :
ot = (hw-40)*(hp*2)
tp = rp + ot
elif hw > 60 or hw == 60 :
ot = (hw-40)*(hp*2.5)
tp = rp + ot
else :
print ("Thanks")
# tax Calculations
if tp == 200 :
tax = float((tp/100)*15)
elif tp > 200 and tp < 300 :
tax = ((tp-200)/100*20) + ((200/100)*15)
elif tp >300 and tp < 400 :
tax = ((tp-300)/100*25) + (((tp-200)-(tp-300))/100*20) + ((200/100)*15)
elif tp >400 and tp == 400 :
tax = ((tp-400)/100*30) + (((tp-200)-(tp-300)-(tp-400))/100*25) + (((tp-200)-(tp-300)/100)*20) + ((200/100)*15)
else :
print ("Thanks")
# Printing Results
print ("Your Salary has been credited")
print ("Regular Pay = ", rp)
print ("Overtime =", ot)
print ("Gross Salary before tax deductions = ", tp)
print ("Income Tax applicable =", tax)
you are using your variables across the entire function but are only defining them in the if/else cases. This adds a lot of room for error of missing a definition somewhere within a case as in
...
if tp == 200 :
tax = float((tp/100)*15)
elif tp > 200 and tp < 300 :
tax = ((tp-200)/100*20) + ((200/100)*15)
elif tp >300 and tp < 400 :
tax = ((tp-300)/100*25) + (((tp-200)-(tp-300))/100*20) + ((200/100)*15)
elif tp >400 and tp == 400 :
tax = ((tp-400)/100*30) + (((tp-200)-(tp-300)-(tp-400))/100*25) + (((tp-200)-(tp-300)/100)*20) + ((200/100)*15)
else :
# NO tax defined here
print ("Thanks")
...
You should define the function-scope variables on the top of your function as:
hw = float(input("Please enter total hours worked"))
hp = float(input("Please enter the hourly rate"))
rp = 0
ot = 0
tp = 0
tax = 0
# Pay and OT Calculations
...
# Printing Results
print ("Your Salary has been credited")
print ("Regular Pay = ", rp)
print ("Overtime =", ot)
print ("Gross Salary before tax deductions = ", tp)
print ("Income Tax applicable =", tax)
By setting these default values you are sure to never miss the variable initialization in your code and you will not need to add extra logic to handle the tax variable in the edge cases where it should not be changed (the else case in your question.
I dont understand why the code doesnt work and they have repeated the questions to me 4 times. and say that float is not callable. i have tried doing this for quite awhile but i dont seem to get anything at all. is there any easier way for python3? I just learnt this language 2 weeks ago. its not a whole new world to me but many of the things i am not familiar with. such as indentation
def get_taxi_info():
flag_down = float(input("What's the flag-down fare: $"))
within = float(input("What's the rate per 400 meters within 9.8km? $"))
beyond = float(input("What's the rate per 350 meters beyond 9.8km? $"))
distance = float(input("What's the distance traveled (in meters)? "))
peak = input("Is the ride during a peak period? [yes/no]")
mid6 = input("Is the ride between midnight and 6am? [yes/no]")
location = input("Is there any location surcharge? [yes/no]")
surloca = float(input("What's the amount of location surcharge?"))
return (flag_down, within, beyond, distance, peak == 'yes', mid6 == 'yes', location == 'yes', surloca)
def calculate_taxi_fare():
dist = get_taxi_info()
if dist[3] > 9800:
extra = (dist[3] - 9800) % 350
if extra == 0:
a = (extra//350) + 22
else:
a = (extra//350) + 23
return a
elif dist[3] <= 9800:
extra = (dist[3] - 1000) % 400
if extra == 0:
a = (extra//400)
else:
a = (extra//400) + 1
return a
def peakornot():
peak = get_taxi_info()
if peak[4] == True and peak[5] == False:
surcharge = 1.25
return surcharge
elif peak[4] == False and peak[5] == True:
surcharge = 1.50
return surcharge
taxifare = calculate_taxi_fare()
info = get_taxi_info()
peak1 = peakornot()
taxifare = calculate_taxi_fare()
if info[6] == True:
payable = ((info[0] + (info[1] * taxifare()) + (info[2] * taxifare())) * peak1[0]) + info[7]
print ("The total fare is $" + str(payable))
elif info[6] == False:
payable = ((info[0] + (info[1] * taxifare()) + (info[2] * taxifare())) * peak1[0]) + info[7]
print ("The total fare is $" + str(payable))
The function calculate_taxi_fare returns a float, so on this line taxifare is a float
taxifare = calculate_taxi_fare()
Therefore you cannot say taxifare() because it looks like a function call, so you can just use for example
info[1] * taxifare

By default, names that you assign to in Python are local to the function in which they are declared. So, if you have:
def main():
total = 0
def payIncrease():
total = 0
total += amount
then you have two independent values named total. One way to solve this is to make it global:
total = 0
def main():
global total
total = 0
def payIncrease():
global total
total += amount
Note that you don't want to assign total = 0 inside payIncrease(), because that would reset your running total to 0. You probably added that when you broke out your code into the payIncrease() function because Python gave you an error without that.
